Drawing Direction Fields Online I am looking for a convenient and free online tool for plotting Direction Fields and Solution Curves of Ordinary Differential Equations. I tried the "Slope Field Plotter" on Geogebra; it worked tolerably well with direction fields, but for solution curves, some funny thing happens like this: ![enter image description here]( My Questions: 1. Why does the solution curve appear to be very different from circles? 2. Is there any alternative online free resources that will do a better job on this? **Edit:** I would love to use WolframaAlpha for this, if it works. Any suggestions on this?

Take a look at this tool:

Found it from the Wikipedia slope field page.
